Page 4: Installation
1. Installation It is suggested the heat exchanger is installed on a level foundation giving enough support to the frame. No special anchorage for the foundation is required, but minimum free space around the heat exchanger is needed. It is necessary to leave enough free space around the heat exchanger to make future service possible. - Page 5 Typical operation mode of plate heat exchanger with parallel and counter current flows A = Cold B = Hot...

2. Function and Operation 2.1 Plate pack assembly The plate pack of a heat exchanger consists of single plates. Plates are always assembled with the gaskets facing the frame plate. Normally there are three kinds of plate in a plate pack. 1. -
Page 7: Start-Up
2.2 Start-up 1. Make sure the plate pack is compressed to the correct ‘A’ measurement before starting up for the first time or after a long period of shut down. It is very important that the system to which the heat exchanger is connected is protected against sudden and extreme variations of temperature and pressure. -
Page 8: Unit In Operation
2.3 Unit in operation Adjustments of the flow rates should be made slowly It is not necessary to monitor the unit continuously in order to protect the system against sudden and while operating, but periodically check that extreme variation of temperature and pressure. ... - Page 9 1. First establish whether instructions exist as to which side should be stopped first. 2. Slowly close the valve controlling the flow-rate of the pump you are about to stop. 3. When the valve is closed, stop the pump. 4. Repeat the procedure for the other side. 5.

Page 10: The Risks Of Not Complying With The Start-Up And Shut-Down Procedures
2.5 The risks of not complying with the start-up and shut-down procedures A liquid in motion in a pipe system represents a lot of energy, and it must be very carefully dealt with. When the liquid flow is stopped it is imperative that this is done smoothly. Note! For this reason fast-closing valves should not be used unless the pipes of the system are very short. -

3. Opening and Closing Warning! If the heat exchanger is hot, wait until it has cooled down to about 40°C. Drain the plate heat exchanger. 4. Loosen then remove the two nuts of the end bolts on the top and bottom of the heat 3.1 A Opening I30, I60 or I100 exchanger, and remove the two plastic end tubes, then mark the plastic end tubes. -

Brush the threads of the bolts clean, using a steel wire brush. - Page 13 12. If the plates are correctly assembled, the edges form a “honeycomb” pattern shown in the 9. Dismantle the two plastic end tubes from end picture. If the plate pack has been marked on the bolts and lubricate the bolt threads with a thin outside, check that the plates have been layer of grease, e.g.

Page 14: Maintenance And Cleaning
4. Maintenance and Cleaning It is suggested to do routine maintenance and extraordinary maintenance for every heat exchanger, the maintenance period depends on physical and chemical properties of the media and the heat load. Routine maintenance It is not necessary to open heat exchanger for routine maintenance, unless a reduction in performance is noted. If this occurs please open the heat exchanger and check the surface of the heat transfer plates. -
Page 15: Extraordinary Maintenance
Extraordinary maintenance Extraordinary maintenance means to inspect all parts 1. Open the heat exchanger. of the heat exchanger completely. 2. Remove gaskets from the plates. Natural acid liquid should be used for extraordinary maintenance, the volume of acid will depend on the level of fouling. - Page 16 Follow steps below to clean oil residues, tar and fats: 1. Open the heat exchanger. 2. Remove gaskets from the plates. 3. Hydrocarbon based deposits may be removed by 4. Dry with a cloth or rinse with water. using a soft brush and paraffin or naphtha based solvent (e.g.
